Plesk and cents OS partitions reconfigure and other bits

I have a centos 6.0 64bit server running plesk The server is migrated and running stable but the partitions have been done poorly and need resizing. As the /Var but has been mounted partition doesn't exist. 'the large partition should have been /var, but it was mounted in /usr' Although this can be fixed using a small work around, id prefer it was all correct and stable. The server is running raid soft 1 . Munin and Fail2ban. First you will need to change all passwords and secure the server, and email the details over You will need to migrate 7.5 gig of data onto your secure server, repartition easily can be done on ovh and redeploy with correct partitions. NO NON PLESK UNDERSTANDING ADMINS NO NOVICES NO PEOPLE WHO DON'T TAKE RESPONSIBILITY NO PEOPLE WHO CANT START GMT 12.00 AT NIGHT NO PEOPLE WHO WANT PAYMENT RELEASED WHILE THE SERVER HAS ERRORS.
